Not really. Magnetism - just like electricity or gravitation - is a "conservative force", which basically means that if you get energy when something moves in one direction, then you NEED the same amount of energy to move it in the opposite direction. For example, it requires energy to lift an object (against the force of gravity); in theory you can recover this energy when the object falls back down.

Where is the Earths magnetic field at its strongest?
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.
What is the relationship between electrical frequency and magnetic field speed for an ac machine?
In an AC machine, the electrical frequency of the input power supply determines the rotational speed of the magnetic field, which interacts with the conductors in the machine to produce electrical power. The relationship between electrical frequency and magnetic field speed is directly proportional – an increase in electrical frequency results in a corresponding increase in the speed of the rotating magnetic field.
Is earths magnetic field the weakest at its poles?
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
Is a compass affected by the earths magnetic field?
Yes, a compass works by aligning itself with the Earth's magnetic field to determine direction. The needle in a compass is magnetized and will point towards the Earth's magnetic north pole.
How big is the magnetic Field?
The strength of a magnetic field is typically measured in units of Tesla (T) or Gauss (G). For example, the Earth's magnetic field is around 25 to 65 microteslas. In comparison, an MRI machine produces a magnetic field of around 1.5 to 7 Tesla.
What is powered by from energy from earths interior?
Volcanoes
Is earths core a source of earths magnetic field?
Yes.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
What is the magnetic field called?
It is Earths' "Magnetosphere".
What is another word for earths magnetic field?
= An effect of the magnetic field is "Van Allen radiation belt" =
What is earths field that reverses from time to time?
The Earth's Magnetic field.
At which location is earths magnetic field the strongest?
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
Which location is earths magnetic field is the strongest?
The strength of Earth's magnetic field is strongest at the magnetic poles, which are not necessarily aligned with the geographic poles. The magnetic field is weakest at the magnetic equator.
